等容量收缩犬左心室的实验表明，心脏交感神经刺激并没有引起心室扩张性的改变。如果心率高到足以产生不完全的心室舒张，交感刺激通过缩短收缩期，在没有任何迹象的情况下恢复松弛的压力-容积关系，然而，心室扩张性被改变。
Experiments with an isovolumically contracting canine left ventricle preparation do not indicate that sympathetic cardiac nerve stimulation induces any alteration in ventricular distensibility. If the heart rate is sufficiently high to produce incomplete ventricular relaxation, sympathetic stimulation, by shortening systole, restores the relaxed pressure-volume relation without any indication, however, that ventricular distensibility is changed.
